Had to give this a shot after reading about using the Zalman7000B-Alcu cooler on video cards in this thread- http://www.xtremesystems.org/forums/sho...d.php?t=86530&highlight=X1800XT+Zalman
The results were better than I could have hoped for. I bought the VF900 recently for my X1800XT and it did an allright job of cooling the card. But I was really hoping to push the voltage more for greater OC'ing with the card.
With the VF900 I could only go up to around 729 core and 873 memory using 1.475 volts before heat became an issue. In BF2 and COD 2 the temps would peak at 81 deg. C.
Now with the 7000B-Cu (I used the all copper version) I can go to 774 core and 891 memory using 1.550 volts. But the best part is my temps in BF2 and COD 2 now top out at only 58-59 deg. C!!! And the AS5 hasn't cured yet so may go down a couple more degrees still.
Probably not the mod for everyone as I now can't use any of my PCI slots below the card because the cooler obstucts all 3. And also had to actually grind down the bottom PCI slot so the fan would clear it.(Looks like my motherboard's warranty just expired- Oh well- just a $65 Chaintech board).
Anyway very happy with the solution it's as quiet as the VF900 and now will never have to worry about the cards temp. again.
Edit- for pics on this better than I could take see the last post in the thread that's linked.
